Windows only: Connectify, the app that quickly turns a Windows 7 laptop into a Wi-Fi hotspot for other devices, has been regularly issuing new betas for a 2.1 version, which both automates more of the hotspot creation process and provides more support for tricky network setups, like bridged network adapters, tethered connections, and resistant wireless network hardware. If you dug the earlier version we wrote up, you'll likely want to upgrade. If you're connecting to an Xbox 360 or PS3, though, you might want to stick with the older version, as a compatibility fix is still being worked out. [Connectify Blog]
